D10 Reference Transport
A Transport Without Compromise
At the heart of the D10 is CH Precision’s innovative MORSE (Mechanically Optimized Reading & Stability Enhancement) laser mechanism. Entirely designed and engineered by CH Precision, MORSE sets unparalleled benchmarks in mechanical precision, stability, and data extraction accuracy. Improving upon the single-material design of the D1.5, the D10’s suspended transport platform employs a sophisticated composite construction—an aluminum skin encasing a dense brass core—that significantly enhances vibration-damping properties and overall mechanical robustness. Supported by alpha-gel isolators and weighing an impressive 13 kilograms, over ten times heavier than its predecessor’s mechanism, the MORSE mechanism effectively suppresses vibrations to below 20 Hz, significantly reducing mechanical noise and preserving the integrity of the digital signal.
Silence. Stability. Sonic Truth.
Among the many innovations in the D10 is a precision circular level mounted directly on the transport. This critical feature allows for exact calibration of the optical pickup, independent of the chassis, optimizing rotational stability and ensuring precise disc tracking. By addressing this often-overlooked aspect of transport design, CH Precision reveals musical nuance, spatial depth, and temporal accuracy that more conventional solutions leave obscured.
A motorized top-loading mechanism provides vertical access to the Disc Vault, sealed by a hybrid-action door that reflects the same engineering precision and intent found throughout. Every mechanical choice has been made in service of the music—capturing each disc with absolute accuracy and unlocking a level of resolution, space, and natural expression that redefines what optical playback can achieve.
The Power Behind Precision
Like all 10-Series reference components, the D10 Reference Transport utilizes a dedicated external power supply (PSU). Engineered with exceptional current and voltage reserves comparable to many power amplifiers, the PSU delivers stable, ultra-clean power to the transport mechanism, minimizing noise and preserving digital signal integrity.
Four galvanically isolated domains independently supply the transport motor, control, DSP, and master clock, eliminating crosstalk and ensuring pristine electrical conditions. Cascaded regulation throughout guarantees consistently clean, stable current to every subsystem. With a total mass of 66 kg (145 lbs) including the power supply, the D10 firmly establishes itself as the ultimate heavyweight in digital reproduction.
CH Precision’s unwavering dedication to engineering integrity guarantees precise, flawless data retrieval from SACD, CD, and MQA CD optical discs. Laser tracking accuracy is maximized, read errors are minimized, and time-domain integrity is preserved. The sonic result is profound musicality: enhanced transparency, expanded soundstage depth, greater low-level detail, and authentic timing and flow, revealing the emotional depth and nuance of every recording.

CH-Control App
Meet the CH-Control App – a control application that allows users direct access to every aspect of their CH system’s set up and use via any Android portable device. The software control systems used to set and monitor the operational parameters of each and every CH component offer the perfect opportunity for remote operation via a portable App.
To use the CH-Control App, all you will need is an Android device and to connect your CH components to an Ethernet network. That can be done either through the Ethernet control board fitted as standard to all CH units, or through the network streaming board that can be installed in C1.2, C1.2 Mono or I1 units. We would always recommend using a dedicated tablet and network for your music streaming and system control requirements.
Once your CH system is all hooked up, the App gives you touch screen access to every setting on every CH component, from your listening seat, a huge benefit when it comes to whole system set up or optimization for individual recordings. Either way, the CH-Control App allows you to make easier and more accurate judgements: Total control, quite literally at your fingertips.
The features of every CH product are accessible through the CH-Control App:
- Built-in UPnP controller to stream dematerialized music, create playlists, etc.
- Set volume level, select sources, reverse phase, mute, etc.
- Access to all the advanced set-up parameters in every CH product.
- Works on a standard Ethernet network.
- The CH-Control App is freely available on Google Play or directly on our website.
